Perfetto is a production-grade tracing platform for Android, Linux, and Chrome that captures extremely detailed information about what a system is doing over time. It’s designed around a low-overhead producer/consumer model: instrumented components (“producers”) write binary events into shared memory buffers and a collector (“service”) reliably streams them to storage. The data model spans kernel and userspace, so you can stitch together CPU scheduling, app lifecycles, binder/IPC hops, GPU work, power and thermal signals, file I/O, heap samples, and more into a single coherent timeline. Perfetto’s ecosystem includes a web-based UI that can load multi-GB traces directly in the browser and an offline “trace processor” that exposes the trace as a queryable SQL-like table schema for deep analysis and automation. ...

pyxntp is a Python module which allows the implementation of a Reference Clock Driver from python, via the xntpd Shared Memory interface.

The mbuff.o module and /dev/mbuff is intended to be used as a shared memory device making memory allocated in the kernel using vmalloc possible to map in the user space. It is especially recommended for RT-Linux tasks/user space communication.

Linux device driver and userspace library to provide for a method to packet capture at high data rates into a user-provided buffer. Tested to line speeds of up to 1Gb without packet loss. ** This project has moved to BitBucket ** https://bitbucket.org/robeden/pcap-ring-mm
